Too wide and falls apart
They are larger than 1.5”, and wouldn’t fit into my grodan smart tray. They need to be cut down, and even when they fit, they fall apart in layers like a biscuit off the bottom. I lost several seedlings due to the material being too easily compressible and not able to retain its structural integrity. I went and got the grodan brand ones and they work better in every way, with the tray I have or not. Don’t try to save money here, just get the good stuff

Rock wool at a good price
I like to use Rockwood for strting my herbs and spices in a hydroponics setup because it holds the monster better and the seeds grow faster. Will by more

Nor happy
This rock wool was cheapest so I purchased it. But it was a terrible mistake. Chunky glass like pieces couldn’t get cuts to push they. Terrible 😞
